Kawamung's medallion

This magical medallion transforms Kawamung from a bogbeast into an ogre mage but removing it reverts him back into his true self. Having predicted that others would try to remove the medallion Kawamung wears a fake one. When Eric returns to the amusement park he is dismayed to find that he still looks like a bogbeast and wears the stolen medallion thinking it will change him back but it does not. Only when Eric returns back to the Realm does he revert to normal but it is not clear whether the medallion is responsible for this, although the camera focuses on it during the transformation suggesting it is.
